Supporting the construction of new urban areas with energy internet

China Energy Storage Network: Recently, the Tianjin Beichen Industrial-City Integration Demonstration Zone was approved by the National Development and Reform Commission. Tianjin Chengdong Power Supply Company actively cooperates with local governments and relevant departments to serve the development of the demonstration zone with high-end energy Internet construction.

On November 3, the energy comprehensive utilization demonstration project of the business center of Tianjin Beichen Industry-City Integration Demonstration Zone was officially started, marking a key step in the integration of urban energy internet into the construction of the northern region of Tianjin. Wu Wenliang, director of the Enterprise Planning and Construction Department of the Management Committee of Tianjin Beichen Development Zone, said that building a high-end industry-city integration demonstration zone requires the support of a high-end energy system.

Connecting services to regional economic transformation and upgrading

Recently, the Beichen Industrial-City Integration Demonstration Zone with a total planned area of ​​68 square kilometers was officially approved by the National Development and Reform Commission. This is the only national-level industrial-city integration demonstration zone approved in Tianjin so far. Previously, the Beichen District Government was committed to turning this precious land into a new urban area with economic development, social harmony, ecological civilization, people's happiness, and a livable and business-friendly environment. The idea of ​​the Beichen District Government is consistent with the strategic concept of the State Grid Tianjin Electric Power Company to build an urban energy Internet. The Chengdong Power Supply Company immediately carried out research and held talks and consultations with the Beichen District Government to plan the planning and construction of the urban energy Internet in the demonstration zone.

On the basis of winning the support of the Beichen District Government, the Chengdong Power Supply Company organized professionals to conduct study and research in many places, including the Northern Branch of the State Grid Customer Service Center, the Sino-Singapore Eco-City in Tianjin Binhai New Area, and the Shanghai Pudong Power Supply Company. It also established a leading group, with professional leaders leading teams to provide door-to-door services in the Beichen Economic and Technological Development Zone many times to understand customer needs, sort out 21 issues such as how customers can save on energy costs, and simultaneously carry out the top-level design of the urban energy Internet.

"As early as two years ago, we established the Beichen District Electricity Service Center with the Beichen District Government, and held regular meetings to promote the progress of projects entering the district. It was through this platform that we, together with the Beichen Development Zone, preliminarily completed the compilation of the "Overall Construction Plan for Urban Energy Internet in the Demonstration Zone" within one month." Yao Zongqiang, director of the Development Department of Chengdong Power Supply Company, said, "This plan is guided by the construction of 'Internet + Smart Energy' and builds an energy Internet system with network, data, service and consumption as the architecture in the demonstration zone. We focus on piloting the application of new energy Internet technologies and practicing new energy management models to achieve innovative breakthroughs in power grid operation and maintenance and services, and turn the demonstration zone into a test field for the construction of urban energy Internet."

The benefits of energy saving and consumption reduction for enterprises are visible

As the first physical project of the demonstration zone's urban energy internet construction, the business center energy comprehensive utilization demonstration project was invested by Beichen Development Zone and constructed by Chengdong Power Supply Company and State Grid Xuji Group. The project uses the roof of the business center, parking lot and adjacent lake resources, and plans to build a wind, solar and storage integrated system through a total capacity of 344.5 kilowatts of solar power generation facilities, 8 5-kilowatt wind turbines, 3 10-kilowatt wind turbines, and a set of lithium iron phosphate battery energy storage units to achieve clean substitution. Through 3 ground-source heat pump units and 16 electric vehicle charging

The construction of piles realizes the substitution of electric energy. The project uses the energy management and control platform to uniformly monitor, dispatch and control the coordinated operation of various energy sources, realize the interconnection and complementarity of multiple energy sources, and coordinate the regulation to ensure the balance of energy supply and demand in the building. After the implementation of the project, the clean energy utilization rate of the building can reach 40%, and the annual power generation of solar energy and wind energy can reach 480,000 kWh. The multi-energy optimization and efficient utilization will increase the energy utilization efficiency of the business center by about 20%. In addition, the demonstration area will also carry out a plan for all-electric drive of public and public vehicles in the park, promote the use of electricity instead of coal, and promote technologies such as ground source heat pumps and electric heating. By 2020, the demonstration area will achieve zero coal consumption.

"This project incorporates the development concept of 'innovation, coordination, green, openness and sharing' during the 13th Five-Year Plan period. Chengdong Power Supply Company has conducted five rounds of demonstrations with the Development Zone and State Grid Xuji Group on the design of the plan in order to achieve the best plan and the best results. I believe that the use of green energy in the future will also attract more high-tech industries with energy-saving and environmental protection needs to continue to flow in." said Wu Wenliang. Yao Zongqiang said: "In order to smoothly promote the project, we have set up a special on-site command center to conduct real-time control, and plan to use this project as a typical example to provide a model of comprehensive energy utilization for enterprises in the area. By encouraging regional enterprises to participate in the construction of the urban energy Internet, the attractiveness of the demonstration zone will be enhanced, and replicable and popularizable experience will be provided for new industrialization."

Build a mutually beneficial and win-win energy service ecosystem

In order to attract more companies with energy-saving needs to use clean electricity, Chengdong Power Supply Company took the project construction as an opportunity to form an industrial alliance with nine units including Tsinghua University, State Grid Xuji Group, and Tianjin University, and established a technical support-product customization-project application alliance mechanism to concentrate superior resources to provide customers with comprehensive energy solutions.

In order to provide high-quality energy services, Chengdong Power Supply Company has created a menu-based service model, introduced a contract energy management model, and established an energy tracking mechanism. Customers can flexibly choose energy usage methods from the energy menu according to their personalized energy needs. At the same time, in order to reduce customers' initial investment, Chengdong Power Supply Company, energy-consuming enterprises and third-party energy-saving service companies cooperate to use part of the energy-saving income to pay for construction costs. After the project is completed, Chengdong Power Supply Company will track energy usage by providing comprehensive analysis reports on energy usage and provide energy guidance to enterprises. At present, 18 enterprises in the demonstration area have participated in energy surveys, of which 5 are conducting comprehensive energy efficiency analysis and 3 are conducting construction plan demonstrations. A win-win energy service ecosystem has been formed.

"In the future, we also plan to set up a production and operation and maintenance monitoring command center in Beichen, create a Beichen high-end smart demonstration zone operation and maintenance management demonstration center, and explore the construction of an active distribution network based on flexible direct current technology, so that the demonstration zone power grid will have the five major characteristics of safety and reliability, high-quality service, economical and efficient, green and low-carbon, and friendly interaction." Yao Zongqiang said confidently.

In order to further spread and promote the important role of urban energy Internet in the construction of energy system, Chengdong Power Supply Company recently launched the Global Energy Internet Beichen Promotion Month with the theme of "Safety, Intelligence, Ecology and Service". It used the Beichen Economic and Technological Development Zone Business Center as a publicity base, organized corporate seminars, invited experts to give lectures, conducted corporate energy consumption questionnaires, and introduced the energy Internet development concept and the changes it will bring to people's future lives to the public, achieving good publicity effects.
